Nix installation fails on macOS

I am trying to install nix multiuser on macOS Monterey 12.0.1. But it fails every time when ~~> Setting up the basic directory structure.

$ sh <(curl -L https://nixos.org/nix/install) --darwin-use-unencrypted-nix-store-volume --daemon

I have tried searching for anything $ find . -iname "*nix*" there is nothing.

Terminal output

Switching to the Multi-user Installer
Welcome to the Multi-User Nix Installation

This installation tool will set up your computer with the Nix package
manager. This will happen in a few stages:

1. Make sure your computer doesn't already have Nix. If it does, I
   will show you instructions on how to clean up your old install.

2. Show you what we are going to install and where. Then we will ask
   if you are ready to continue.

3. Create the system users and groups that the Nix daemon uses to run
   builds.

4. Perform the basic installation of the Nix files daemon.

5. Configure your shell to import special Nix Profile files, so you
   can use Nix.

6. Start the Nix daemon.

Would you like to see a more detailed list of what we will do?
[y/n] n


---- let's talk about sudo -----------------------------------------------------
This script is going to call sudo a lot. Every time we do, it'll
output exactly what it'll do, and why.

Just like this:

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo echo

to demonstrate how our sudo prompts look


This might look scary, but everything can be undone by running just a
few commands. We used to ask you to confirm each time sudo ran, but it
was too many times. Instead, I'll just ask you this one time:

Can we use sudo?
[y/n] y

Yay! Thanks! Let's get going!

~~> Fixing any leftover Nix volume state
Before I try to install, I'll check for any existing Nix volume config
and ask for your permission to remove it (so that the installer can
start fresh). I'll also ask for permission to fix any issues I spot.

---- Found existing Nix volume -------------------------------------------------
  special:	disk1s7
     uuid:	9215B0B8-28C2-4888-A4A1-392E648D6BD6
encrypted:	yes

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo security find-generic-password -s 9215B0B8-28C2-4888-A4A1-392E648D6BD6 -w

to confirm keychain has a password that unlocks this volume

Password:
Verifying the specific cryptographic user 9215B0B8-28C2-4888-A4A1-392E648D6BD6 on APFS Volume disk1s7
Passphrase valid
Found a working decryption password in keychain :)


During install, I add 'nix' to /etc/synthetic.conf, which instructs
macOS to create an empty root directory for mounting the Nix volume.

Nix isn't the only thing in /var/folders/ql/ydkc2hhx4cv0541yvdk9pzmw0000gn/T/tmp.PWDLiERZdv/synthetic.conf.edit,
but I think I know how to edit it out.
Here's the diff:
+ nix
  run	private/var/run
Does the change above look right?
[y/n] y


---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo cp /etc/synthetic.conf /var/folders/ql/ydkc2hhx4cv0541yvdk9pzmw0000gn/T/tmp.PWDLiERZdv/synthetic.conf.edit

remove nix from /var/folders/ql/ydkc2hhx4cv0541yvdk9pzmw0000gn/T/tmp.PWDLiERZdv/synthetic.conf.edit

During install, I add '/nix' to /etc/fstab so that macOS knows what
mount options to use for the Nix volume.
Can I remove /etc/fstab?
[y/n] y


---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo rm /etc/fstab

to remove /etc/fstab


The installer adds a LaunchDaemon to mount your Nix volume: org.nixos.darwin-store
Can I remove it?
[y/n] y


---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo launchctl bootout system/org.nixos.darwin-store

to terminate the daemon


---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo rm /Library/LaunchDaemons/org.nixos.darwin-store.plist

to remove the daemon definition

---- Preparing a Nix volume ----------------------------------------------------
    Nix traditionally stores its data in the root directory /nix, but
    macOS now (starting in 10.15 Catalina) has a read-only root directory.
    To support Nix, I will create a volume and configure macOS to mount it
    at /nix.

~~> Configuring /etc/fstab to specify volume mount options

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo /usr/sbin/vifs

---- sudo execution ------------------------------------------------------------
I am executing:

Jeeze, something went wrong. If you can take all the output and open
an issue, we'd love to fix the problem so nobody else has this issue.

:(

We'd love to help if you need it.

You can open an issue at https://github.com/nixos/nix/issues

Or feel free to contact the team:
 - Matrix: #nix:nixos.org
 - IRC: in #nixos on irc.libera.chat
 - twitter: @nixos_org
 - forum: https://discourse.nixos.org

I’m not sure why diskutil it isn’t already on your PATH, but I wonder if running export PATH="/usr/sbin:$PATH" before you start the installer will fix it?
